Liu, Be sure to use the patched QEMU from the website. I believe the manual gives the link. I believe you can also download the 0.5.0 toolkit and it have both insight, gdb, and the patch qemu. Like yourself, I did see issues when I did a fetch from the Git repo. I believe the codezero team will be releasing some new code soon (according to emails and mail-serv posts) that should help with ARMv7 development.

With the Git version and follow the http://www. l4dev.org/build_from_scratch document, We can produced a "final.elf" for PB926-Versatile Platform & ARM926EJ-S processor with an "empty" or "hello_world" baremetal project, but when you run the final image with qemu & gdb debugger, and after the following messages: ELF Loader: Loader image size: 557KB, placed at physical 0xe00000 - 0xe8b6b8 Loading the kernel...

FSR: 0x1f, FAR: 0xa00040ec, PC: 0xa0001d2c pte: 0x104ffe CPU0 Exiting. this message seems is come from file src/arch/arm/exception-common.c, function fault_ipc_to_pager(), line 121, I don't know if this is a bug or not, because in my mind, the correct message should be come from file conts/baremetal/hello_world/hello,c, function print_hello_world(), line 10, which as following: cont0: Hello world from hello_world0! but my test result always failed after init_finalize(). So, that means I do not believe that someone said that their demos which also come from the codezero's Git repository can working. Am I wrong? By the way, especially for Amit and B-labs R&D team, I found a small bug in file print-early.c(all of the platform), function printhex8, line 51 & line 54(this line numbers means in the pb926 platform version, for realview platform's version is line 58 & 61, beagle's version is line 50 & 53), the correct code should like this: 51 *temp = '\0'; 52 53 if ( !val ) { 54 *(--temp) = '0'; Am I right?
